LTC6605CDJC-10#TRPBF

Overview

The LTC6605CDJC-10#TRPBF is a dual matched 10MHz lowpass filter with differential amplifiers. It features two independent channels with adjustable -3dB cutoff frequencies ranging from 9.7MHz to 14MHz. The device operates on a supply voltage between 2.7V and 5.25V, drawing up to 33.1mA per channel in full power mode. It provides pin-selectable gains of 0dB, 12dB, or 14dB and includes three-state BIAS pins for power management. The component is housed in a compact 22-pin 6mm x 3mm DFN package.

Feature Summary

• Dual fully differential amplifiers configured as matched second-order lowpass filters
• Pin-selectable gain configurations including 0dB, 12dB, and 14dB options
• Three-state BIAS control allowing selection between shutdown, medium power, and full power modes
• Adjustable output common mode voltage via dedicated VOCM pins

Applications

• Broadband wireless ADC driver and filtering
• Antialiasing filter applications
• Single-ended to differential signal conversion
• DAC smoothing filter implementation
• Zero-IF direct conversion receivers

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the 'C' grade designation corresponds to the commercial temperature range of 0°C to 70°C rather than the extended industrial range. Ensure compatibility with the required 22-lead DFN footprint during procurement planning.

Selection Notes

Select this component for applications requiring precise channel-to-channel phase and gain matching. Verify that the input common mode voltage range aligns with the system's signal levels relative to the supply rails. Consider the external resistor requirements if a specific cutoff frequency outside the default 9.7MHz setting is necessary for the design.

Part Context

This part belongs to the LTC6605 family of programmable analog signal processors. The CDJC-10 variant specifically denotes the commercial temperature grade and the 10MHz nominal filter characteristic. It serves as a high-performance solution for driving differential input analog-to-digital converters in communication systems.

Replacement Considerations

The LTC6605IDJC-10#TRPBF is a verified substitute offering the same electrical performance but guaranteed over an extended temperature range of –40°C to 85°C.
